THILL-COUPLING.

SPECIFICATION forming part Of Letters Patent No. 635,183, dated October17, 1899.

Application filed Tune 21, 1899. Serial No. 721,322. (No model.)

To all whom it may concern:

Beit known that I, THOMAS E. PIPER, of Blairsville, in the county ofIndiana and State of Pennsylvania, have invented a new and ImprovedThill-Ooupling, of which the following is a full, clear, and exactdescription.

This invention relates to a thill-coupling adapted to provide means forsecurely holding the thill and at the same time permitting theconvenient detachment thereof, the device being designed to overcome thedisadvantages resulting from old constructions which render theattachment and detachment of the thills a comparatively lengthy task.

This specification is the disclosure of one form of my invention, whilethe claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of the invention with parts in section.Fig. 2 is a plan view thereof, and Fig. 3 is a similar view with theparts in open position.

The coupling comprises a forwardly-elongated body portion 4, held to theaxle by means of'a clip 5 and having at its front end an upwardly andrearwardly extended hook 6, the terminal edge of which is disposeddiagonally with respect to the body portion, as shown in Figs. 1 and 2.This hook 6 holds the trunnions 7 of the thill 8, and the body portion 4is provided with a rubber cushion 9, serving to deaden the soundoccasioned by the movement of the several parts.

A latch-section 10 is mounted to swing horizontally on the top of thebody-section l by means of a stud 11, at the top of which is a washer12, bearing on the latch-section and held by a screw 14. Thislatch-section has a diagonallydisposed front end adapted to match withthe diagonal end of the hook 6, so as to eftectually close the hook, asshown in Figs. 1 and 2. The latch-section is held in closed position bymeans of a dog 15, pivoted on a transverse pin 16 and thrown into normalor closed position by a torsional spring 17, coiled around the pin andbearing against the dog and against the latch-section. The

dog 15 has one end bent downward to form a bolt 18, engaging in a recess19 in the body 4 of the coupling, and the other end of the dog is bentupwardly and forwardly to form a finger-piece 20, extending through aslot 21, formed in the top portion of the latch-section.

The dog is situated within a cavity 22, formed in the latch-section 10.When the latch-section is in closed position, the bolt 18 bears in therecess 19 and holds the latch-section. By pressing down the finger-piece20 the dog may be thrown to raise the bolt 1S out of the recess 19, thuspermitting the swinging of the latch-section and the consequent openingof the coupling.

It will be seen that by means of this construction il is possible tovery easily and quickly apply and disengage the coupling and that thecoupling when once secured will hold the thill in the most reliablemanner.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A thill-coupling, having a body portion with ahook thereon, the end of the hook being beveled, alatch-section mountedto swing on the body-section and having a beveled end matching with thebeveled end of the hook, and a dog acting between the latch and bodysections and serving to hold the two sections in locked position.

2. A thill-coupling, havinga body-section with a hook thereon, alatch-section mounted to swing on the body-section and serving to closethe hook, a pin extended through the latch-section, a dog mounted in acavity in the'latch-section and turning on the pin, and a springpressing the dog and throwing the same into .locked engagement with thebody-section, the dog having one end projected upwardly through a slotin the latch-section, such end forming a linger-piece.

3. A thill-coupling, having a body portion with an upwardly andrearwardly projecting hook, a latch-section mounted .to swing on thebody portion to close the hook and inclose the trunnion of the thill,and a dog located inward of the hook and having a downwardlyextendedbolt acting between the latch and body portion to hold the latch inclosed position.
